Material Processing

Pelletizing & Granulation

FEECO offers a variety of agglomeration equipment for mixing, pelletizing, and granulating sulfur products. This includes pin mixers, disc pelletizers, drum granulators, and pugmill mixers.

Drying & Cooling

FEECO rotary dryers and coolers are robust and built for reliable sulfur processing in any setting.


Coating is essential to maintaining product integrity when working with sulfur. FEECO coating drums provide a superior coating result with uniform and even coating distribution.

Bulk Material Handling

FEECO also provides a comprehensive line of bulk material handling equipment for all of your sulfur handling needs. We offer custom bucket elevators, belt conveyors, reversing shuttle conveyors, and steep incline conveyors, along with equipment to increase the flexibility of your handling system, such as belt trippers and plows, and belt feeders.


We can supply a single piece of handling equipment to fit into your existing process, or a complete bulk handling system as part of an overall process solution.


Plant and Pilot Scale Process Testing and Design

The FEECO Innovation Center is a unique testing facility where we can test your material at both batch and pilot scale in order to work out process variables and design commercial-scale units, as well as scale up the process.

The FEECO Innovation Center is well-equipped to suit a wide range of testing needs, including pelletizing, drying, and roll compaction. We can test on a single piece of equipment, or a continuous process loop.


Please note that the Innovation Center does not work with molten sulfur unless it is pre-ground. 


We offer comprehensive testing services in four categories:

Feasibility/Proof of Concept: An initial, non-witnessed batch testing phase in which the possibility of creating a product is explored.
Proof of Product: A more in-depth batch testing phase in which more time is spent determining whether a product can be made to desired specifications.
Proof of Process: A continuous testing phase that aims to establish the equipment setup and parameters required for continuous production of your specific material.
Process/Product Optimization: An in-depth study to optimize your specific material’s characteristics and/or production parameters in an industrial setting.
